If a search finds multiple rows I want to display them, I don't know if the while loop needs to be in my query function, or if I need to use /mysql_fetch_assoc()/

//this works and pulls in 1 record

function get_order_info($search_value, $search_field, $table){

	global $mysqlconn;

	$query_error="Data Not Found";

	// building query 

	$query="SELECT * ";

		if($table=="usps"){

			$query .="FROM ". USPS_TABLE ;

		}

		else{

			$query .="FROM ". UPS_TABLE ;

		}

	$query .= " WHERE ". $search_field;

	$query .= " = ". $search_value;

	$query .= " LIMIT 0, 10";

	

	$query_result_set = mysql_query($query, $mysqlconn)

	

	//this test to see if there is actual data will reurn false if the query cannot find anything

	if($order_info= mysql_fetch_array($query_result_set)){

		return $order_info;

	}else{

		return $query_error;

	}

}

You were close, just need a while loop.
<?php

function get_order_info($search_value, $search_field, $table){

        global $mysqlconn;

        $query_error="Data Not Found";

        // building query 

        $query="SELECT * ";

                if($table=="usps"){

                        $query .="FROM ". USPS_TABLE ;

                }

                else{

                        $query .="FROM ". UPS_TABLE ;

                }

        $query .= " WHERE ". $search_field;

        $query .= " = ". $search_value;

        $query .= " LIMIT 0, 10";

        

        $query_result_set = mysql_query($query, $mysqlconn)

        

        

        while ($row = mysql_fetch_array($query_result_set))

{

       //Do what every you want to do with your data here, it will loop

       //through the results row by row

}
 

    return $yourResults;

?>

So now I would return $row and out of the while loop return the query_error()

ok here is the code and i want to display multiple rows if there is any. My form brings in a search string, my main <?php> block checks for the post variable;
//This is main .php page calls functions
 

<?php

$table="usps";
 

//Form validation check for search 

if(isset($_POST['form_zipcode'])){

 while($sel_order=search_for($_POST['form_zipcode'], $table_field,$table)){

    echo output_track_info($sel_order);

  }

}else{

  echo "Enter a search above.";

}

?>
 
 
 

//functions.php
 
 

function search_for($form_result, $table_field, $table){

    $end="END OF SEARCH";

    //Call functions to get array data, and clickable link data 

    while($result= get_order_info($form_result, $table_field ,$table)){

	return $result;

    }

    return $end;

}
 
 
 

function get_order_info($search_value, $search_field, $table){

 global $mysqlconn;

 $end="END OF SEARCH";

 $query_error="Data Not Found";

	

 // building query 

 $query="SELECT * ";

  if($table == "usps"){

   $query .="FROM ". USPS_TABLE ;

  }

  else{

   $query .="FROM ". UPS_TABLE ;

  }

  $query .= " WHERE ". $search_field;

  $query .= " = ". $search_value;

  $query .= " LIMIT 5, 10";
 

  $query_result_set = mysql_query($query, $mysqlconn);

  //this test to see if there is actual data

  if(!$query_result_set){

	die("Failed to find search criteria ". mysql_error());

  }else{

       while ($row = mysql_fetch_array($query_result_set)){

	return $row;

       }

  }

	return $end;

}

You can also return the result as a global array if you need to use the recordset later.

Is there a particular field you are interested in extracting?

//This is main .php page calls functions

 

<?php

$table="usps";

 

//Form validation check for search 

if(isset($_POST['form_zipcode'])){

 while($sel_order=search_for($_POST['form_zipcode'], $table_field,$table)){

    echo output_track_info($sel_order);

  }

}else{

  echo "Enter a search above.";

}
 

?>

 

 

 

//functions.php

 

global $data;

 

function search_for($form_result, $table_field, $table){

    $end="END OF SEARCH";

    //Call functions to get array data, and clickable link data 

    while($result= get_order_info($form_result, $table_field ,$table)){

        return $result;

    }

    return $end;

}

 

 

 

function get_order_info($search_value, $search_field, $table){

 global $mysqlconn;

 $end="END OF SEARCH";

 $query_error="Data Not Found";

        

 // building query 

 $query="SELECT * ";

  if($table == "usps"){

   $query .="FROM ". USPS_TABLE ;

  }

  else{

   $query .="FROM ". UPS_TABLE ;

  }

  $query .= " WHERE ". $search_field;

  $query .= " = ". $search_value;

  $query .= " LIMIT 5, 10";

 

  $query_result_set = mysql_query($query, $mysqlconn);

  //this test to see if there is actual data

  if(!$query_result_set){

        die("Failed to find search criteria ". mysql_error());

  }else{

       $x=0;

       while ($row = mysql_fetch_array($query_result_set)){

	foreach ($row as $key => $value){

         $data[$x][$key]=$value

        }

	$x++;

       }

   return $data;

  }

}

Typo fixed.

Again is there a certain field you need for the tracking function?

if so instead of the forloop you could do:
$data[$x] = $row['{field_name_here}'];

//This is main .php page calls functions

 

<?php

$table="usps";

 

//Form validation check for search 

if(isset($_POST['form_zipcode'])){

 while($sel_order=search_for($_POST['form_zipcode'], $table_field,$table)){

    echo output_track_info($sel_order);

  }

}else{

  echo "Enter a search above.";

}
 

?>

 

 

 

//functions.php

 

global $data;

 

function search_for($form_result, $table_field, $table){

    $end="END OF SEARCH";

    //Call functions to get array data, and clickable link data 

    while($result= get_order_info($form_result, $table_field ,$table)){

        return $result;

    }

    return $end;

}

 

 

 

function get_order_info($search_value, $search_field, $table){

 global $mysqlconn;

 $end="END OF SEARCH";

 $query_error="Data Not Found";

        

 // building query 

 $query="SELECT * ";

  if($table == "usps"){

   $query .="FROM ". USPS_TABLE ;

  }

  else{

   $query .="FROM ". UPS_TABLE ;

  }

  $query .= " WHERE ". $search_field;

  $query .= " = ". $search_value;

  $query .= " LIMIT 5, 10";

 

  $query_result_set = mysql_query($query, $mysqlconn);

  //this test to see if there is actual data

  if(!$query_result_set){

        die("Failed to find search criteria ". mysql_error());

  }else{

       $x=0;

       while ($row = mysql_fetch_array($query_result_set)){

	foreach ($row as $key => $value){

         $data[$x][$key]=$value;

        }

	$x++;

       }

   return $data;

  }

}
